Take it to your local Schwinn dealer, they have catalog parts available for restoring antique bikes. I did my dad's 1957 Schwinn and my uncle's '49 Schwinn. They sell replacement rims, handlebars, even decals for after you paint it. Word of caution though. If its a "coaster brake" bike, even if the rear axle is shot save the rim and the brake bar. Many of the older ones have a serial number that relates to the year of manufacture. If yours does, this helps prove the year, thus helping establish value.
